of gas lamps, the novel features of the invention'being particularlysuited to multiple: burner lamps of the inverted type.

The invention resides in the several tea-v tures'l'iereinafterparticularly described and claimed and embodied in the lamp illus-ltrated :in the accompanying drawing in; which Figure 1 is an elevationof a multiple burner gas lamp in which the casing and;

globe are shown in section exposing theinterior; F ig. 2' is a sectionalview of the. burner, manifold and connected. piping; Fig. 3 is a"section taken in the direction of; the arrows on line 33 of Fig. 2; andFig. at is a section taken in the direction of the arrows on line H ofFig. 3.

Referring to the drawings, the lamp is supported by the supply pipe Awhich is.

screwed into the upper endof a fitting B,-

the lower end of which fitting in turn screwed into a tapped hole in thecenter of a bridge n extending across the lower half C of ahollowmanifold ring which is preferably concentricwith the pipe A- A plug l)is screwed upwardly into the tapped hole in the bridge a and serves as aclosure for a well 6' in the fitting B the purpose of whicn. will bemore -t'ully described hereinafter. A suitablenuniber of nipples E arescrewed, into bosses on the under side of the lower half C of themanifold, these nipples E being equally spaced about the ring and Iprovided upon their lower extremities with "refractory burners'F uponwhlch inverted mantles G are placed. .Anuppcr halt D of the manifoldring is placed 'upon the lower half C, an annular screen H beniginterposed between the two halves dividing the annular space within themanifold into upper and lower chambers. The two halves C and D aresecuredtogether by a suitable number of screws (Z.

Acasing is provided for the lamp which casing consists impart.

of a cylindrical flue or'cltimney I which extends upwardly from a pointjustabove the burners F andincloses the ring manifold and nipples E. Anornamental: hood J surrounding the lower end. of the flue I serves tohold a glass globe K. Perforations j are provided in the hood Jimthejexit of heated air anda small perforation hat the lowermost part ofthe globe K affords entrance for air to the globe. heat bell L is supported on the supplyjpipe A some distance above the'upper endof the-flueI. An air funnel M of axbunsen. has a threaded end which is passedthrough'an aperture in the wall of the duel and isscrewcd into a boss onthe upper halt D of the manifold ring and this funnel is provided withair inlet apertures which may rbeclosed or opened. to

any desired degree by. the rotation of a shutter m mounted upon the,funnel.

' A valve housing N is'coniieo'ted to. the air funnel M by a threadednipple-O which is provided with a jet opening "adapted to be regulatedbythe needle valve P threaded into the housing Niin alineinentwith nippleO. A cock Q is mounted in tlievalve housing N to-open and close apassageway V which communicates with the jet opening in nipple O. Theouter end of thepassageway V is closed by a threaded plug a which. maybe removed to give access to the passageway V in order that ittmhy; becleaned. A pipe R is screwed intothe valve housing N and opens into thepassageway V abovethecock Q. This pipe passes through an opening in theWall ofthe line I and is connected by a union 7' to the upper end of,the'fittingB. The casing is mainly supported at the junction of thefunnel M and the inanifold ringv and by a bridge piece 8 at the top ofthe fine I engaging the'pipe A.

A pilot light leads from the passageway ice eway V during alternatedownstrokes is nio'untby' the lever X engages one tooth of the ratchet-Uand turns the cock Q one-quarterv revolution each time the lever Xismoved downwardly. The lever X is automatically returned by a spring Yafter each downward movement.

The manner in which the gas is led to the burners is as follows: Flowingin through the supply pipe A the gas is directed into the well 5. whereany particles that may have been carried by the gas collect and are notcarried intothe needle valves and small parts from which their removalwould be troublesome. In order to remove such particles and dirt as mayfrom time to time c01- lect in well I) it is only necessary to removeplug 6 which is'so located as to be easily accessible. After havingdeposited any dirt or particles that it may have carried, in the well 6the gas flows through the pipe R into the upper end of the as sagewayV.. From this point gas ows through the adjustable needle valve T to thepilot light pipe and the flow of gas to the pilot light is notinterrupted by the operation of the cock, Q. However if at any time itis desired to discontinue the supply of gas to the pilot light this canbe done by entirely closing the needle valve T. The supply of gas forthe burners is admitted to the lower end of thepassageway V when thecock Q is 'openpd and passing by the needle valve P is directed throughthe air funnel M and from thence passes together with a suitablequantity of air drawn from without the casing of the lamp, .into themanifold ringabove the screen H; The chamber within the manifold ringand above the screen H first fills with gasand air distributlng the gas"and air before they pass downwardly through the screen H and evendistribution of well mixed gas and air is assemblage the down thenipples E efiected by the time the mixture reaches mouths of and passesleading to the burners. The relatively large area of the screen Hpermits the mixture to pass quietly to the burners and prevents roaring.It will be noted that the arrangement of the several parts as shown ispeculiarly advantageous in lamps of this character, affording centralsupport by the supto the drip and dirt thoroughly practical of theprincipal parts, well adapted to the ornamental designs so essential inthis type of lamp.

It is obvious that various minor changes collecting well and a in formand detail may be made Without departing from the spirit of theinvention.

Having thus described my invent-ion what I claim is:

1. In a gas lamp, the combination of a supporting vertical gas supplypipe, a catch-all well forming a downward continu ation of said supplypipe, a burner having a same,

supporting member provided with an opening having a removable closure inthe lower end 'of said opening, said catch-all well being connected withthe upper end of said opening in the supporting member, whereby accessmay be had to said catch-all well, substantially as described.

2. In a gas lamp, the combination of an upright flue, a gas supply pipeextending downwardly into said flue and terminating in a well, a ringmanifold surrounding said Well and supported therefrom, a branch gasduct leading laterally from said supply pipe through the wall of saidflue to the outside thereof, an air and gas duct leading from outsidesaid fluethrough the wall thereof to said manifold, and controlling andmixing devices located outside said flue and connecting said ducts;substantially as described.

3. In a gas lamp, a supporting vertical gas supply pipe, a catch-allwell forming a downward continuation of said supply pipe, a ringmanifold concentric with and surrounding said well,'a casing for saidlamp, a conduit branching from said supply pipe above said catch-allwell v passing outside said casmg'and again passinginto said casing toconnect with said manifold, a bunsen I located in said conduit outsidesaid casing,

and a removable closure at the lower extremity of said catch-all well,said catch-all well extending through and projectihg below said manifoldto render said closure accessible; substantially as described.
